A blood-clotting “super gel.” A mobile app for heart attack recovery. A pizza-delivering drone. A souped-up walker for pediatric ICU patients. Johns Hopkins engineering students have plenty to show off on Tuesday at the annual Design Day.

Engineering students will present the projects they’ve spent a semester or more working on as part of Engineering Design Day—the annual year-end Whiting School of Engineering event in which students tasked with designing solutions to real-world problems display their research, devices, and prototypes.

A reusable cryotherapy system that could bring low-cost breast cancer treatment to women in rural South Africa has won the bronze prize for a Johns Hopkins University biomedical engineering team in the undergraduate category of the 2016 National Collegiate Inventors Competition.

An undergraduate team from Johns Hopkins University has been named a finalist in the 2016 Collegiate Inventors Competition. The team improved on a cryotherapy device developed by Johns Hopkins students for use in rural Africa, where women who are diagnosed with breast cancer often have limited access to treatment.
